9. In the upper portion of in one side of the same is v communicates with an upwardly extending ofsheet metal with a rounded ing depth bottom edge which is a into the shoulder 8 and rest upon the the body a 'port 10 which fuel pipe 11 which joins the'body 'E- at'an acute angle and is preferably attached there to. The lower end of. pipe 11 fits into and rests upon the flanged shoulder 12 on the top of the supply pipe 13, similarly to the manner in which the body E rests upon the top of base C, so that the-body O with its attached pipe 11 maybe lifted from place when desired, as, for instance, to permit access to the doorB.

14 is a ring in the top of body E to facilitate its removal, or in the drawings, vided with my distributers, I locate t eir pipes 1111 on their adjacent sides and mount the lower ends of said pipes onthe fiangedshoulders 12-12 'of the duplex end of the supply pipel3. Valves 15-l5 are provided for the duplex upper end of pipe 13 so that the fuel may be out off or admitted to either distributer at pleasureorthe amount of fuel admitted thereto regulated.

replacement. Where, as

I prefer to make the lower end of pipe 13' also duplex and connected with the discharge pipes l6-16 of the pair of pulverizersF- or other source of pulverized fuel supply. Valves 17-l7 are provided in the lower duplex end of pipe 13 so that either pulverizer may be cut ed as required. When one pulverizer -becomes disabled, the other may be put into commission, so that the fuel supply to the furnaces is continuous.

' The operation of my invention is as fol- The valve. 17 of one or both of the pulverizers is -opened and fuel admitted to the-pipe 13 whence it passes through the pipe or pipes 11 to the distributer or dis tributers, as indicated by the adjustment of the valves. Entering the distributer, the fuel is reverberated by the rounded top of the same and passes down through the body uniformly distributed throughout the extent of the same and through the slot Qinto the furnace. The quantity of fuel admitted through the slot 2 or any portion thereof may be adjusted by means of the dampers 5-5, and the amount of the fuel admitted to the distributer from the supply pipe 13 by means of the valve 15. f

'What I desire to claim is -l. In apparatus for the [purpose dedistributer base mounted for repairs -or adjacent furnaces are ro-.

2. In apparatus for the purpose dcscribed, the combination of a furnace haw ing a vertical opening in 'thetop thereof, a on said furnace and communicating with said opening, a distributer body having a closed rounded top mounted vertically on said'base, a main fuel supply pipe adjacent to said furnace,and a second fuel supply pipe mounted .011 said main pi e and leading upwardly into said bodywl fich introduces the fue upwardly the top thereof, a distributor having a closed rounded. top

3. In apparatus for scribed, the combination of a plurality of furnaces provided with vertical openings in their tops, a distributer having a closed rounded top mounted vertically on each of said furnaces and communicating with said openings, a main fuel supply pipe communicating with the source" of fuel supply adjacent to said furnaces, and branch pipes leadin from said main pipe upwardly into said dlstributers by which said fuel is introduced against said rounded tops by which said fuel is reverbera'ted downwardly through said distributers into the furnaces. 4:. In apparatus for the purpose described, the combination of a plurality of furnaces provided with vertical openings in their tops, :1 distributer having a closed rounded top removably mounted in a vertical position on top of each. furnace and communicating with'the opening thereof, a mainfuel supply pipe communicating with the source of fuel supply adjacent to said furnaces, and branc pipe s removably mounted on said main pipe and leading .upwardly into said distributers by which sa'd fuel is introduced against the rounded top; by which said fuel is reverberated downwardly through said distribu'ters into the furnaces.
